instead of adding hours only via ticket fields, there is a separate view for managing ticket hours. /hours/<ticket number> displays the accrued hours for a particular ticket with a timeline-like view, but should also allow adding of new hours (by default, on "today", but this should be changeable via dropdown menus for day, month, year, etc), editing previously entered hours (amount, date, description) and deleting previously alloted hours if you have the appropriate permissions (TICKET_ADD_HOURS for your own hours, TRAC_ADMIN for the hours of others).

a management and query view is at /hours. This view displays the hours for all tickets for a given time period (last week, by default) in a way that combines the query interface for querying tickets and the timeline display for hours on the tickets in the time period. Query filters are available to find hours for people, hours for tickets of a certain component, etc.

hours are uniquely assigned to tickets and people

hours may have a description, which should be displayed in the applicable views; if a description is provided, the hours and description are logged to ticket comments

Tickets have links to /hours/<ticket number> as the total hours field so that a user can add and view hours for the ticket

Hour tracking and estimation is most useful when the following questions can be answered:

How much time has been spent on a project?

How much time remains in a budget (estimate for a project)?

How much time have we committed to for the next time period ?

How much time is a developer committed to over the next time period?

If we put hour estimates on tickets, assign tickets to people, associate
tickets with milestones, and give milestones due dates, TracHours can generate reports to answer those questions.

The TracHoursSidebarProvider component uses the TicketSidebarProviderPlugin (if enabled) to add a form to each ticket for direct addition of hours to the ticket. Hours will be logged as the authenticated user and comments will not be made.

The TracHoursByComment component enables adding hours by ticket comments. Comments containing snippets like 5 hours, 1 hour, 3.7 hours, or 0:30 hours will be added to the total hours for the ticket, if the commenter has the TICKET_ADD_HOURS permission.

The TracHoursPlugin exports RSS from the /hours handler. This has
been utilized in consumption to provide hours reports across projects
sharing the same parent directory. If trachours.multiproject is
enabled, then /hours/multiproject will become a handler front-ending
hours reports throughout the project and a link to this will appear on
the /hours page to /hours/multiproject.

The multiproject report breaks down hours by project and worker giving
row and column totals. If there are no hours for a project then that
project will not be shown.
